Title: Constant flow valve fitting structure and snap ring thereof
Inventor: SHIRAHATA KOJI
IPC: F16K13/00
Filed: 1996-11-25
Abstract: PROBLEM TO BE SOLVED: To prevent occurrence of hunting noise, to make a constant flow valve unremovable even if reversed water pressure is applied on it and facilitate fitting and removal thereof. SOLUTION: This constant flow valve fitting structure is made simple such that, when reverse water pressure is produced inside a passage pipe 10 and a constant flow valve 20 is applied with force in the withdrawing direction, such force formed on the inner circumferential edge of a ring shaped snap ring 30 is received by elastic pieces 36, which elastically abut upon the constant flow valve 20 in the same direction as the current and which bent and attempt to push the snap ring 30 outward, while a stopper claw 34 formed on the outer circumferential edge of the snap ring 30 correspondingly to the elastic pieces 36 thrusts into a recessed portion 14 formed on the circumferential wall inside the passage pipe 10 in a depression and prevents the constant flow valve 20 from slipping out by the stopper claw 34 of the snap ring 30 not falling off from the recessed portion 14.  Thus not only can fitting and removal work of the constant flow valve 20 be facilitated but it can also be made inexpensively, hunting noise prevented and not removable even if reverse water pressure is applied thereto.

Title: Method for automatically adjusting bpf in fm signal detector
Inventor: IMAI KATSUMI
IPC: H03L7/093
Filed: 1994-12-16
Abstract: PURPOSE: To provide an FM signal detector capable of operation even at low power supply voltage because it is suitable for IC formation and portable. CONSTITUTION: The FM signal detector is provided with a 1st BPF 50, VCO 6, phase comparator 5, filter 7, DC interrupting filter 14, bias circuit 16, comparator 17, zapping circuit 100, and adder 101. In the case of adjusting the center frequency of the 1st BPF 50, a feedback loop to which the output signal of the phase comparator 50 is fed back is interrupted so that the VCO 6 is oscillated by free run. The oscillation frequency of the VCO 6 is set to a required value by impressing the oscillation frequency adjusting control voltage of the VCO 6 to the terminal of the comparator 17 to which an output signal from the filter 7 is impressed and the center frequency of the 1st BPF is roughly adjusted.  Then a test signal is impressed to the 1st BPF 50, and while observing the output signal of the 1st BPF 50, a control signal for fine adjustment is generated from the zapping circuit 100 to finely adjust the center frequency of the 1st BPF 50.

Title: Magnet rotor and high power ac machine therewith
Inventor: SHIRATORI SATORU
IPC: H02K15/03
Filed: 1997-10-31
Abstract: PROBLEM TO BE SOLVED: To prevent rotational dislocation between a back yoke and a permanent magnet, and provide a magnet rotor and a high power AC machine therewith. SOLUTION: A magnet rotor 1 is fitted with a permanent magnet 5 closely- attached to a fitting surface 4 of a back yoke 3 by forming the outer periphery shape of the back yoke 3 into a hexagon. Therefore, the permanent magnet 5 is prevented from rotational dislocation being caused against the back yoke 3 even when high rotational torque acts on it. The back yoke 3 is formed into a hexagon. Therefore, the thickness of only the permanent magnet 5 can be increased at a central part without need for changing the contact width or leakage flux between an N-pole and an S-pole, so that flux density becomes higher to increase output. A sleeve 10 is pressed into the step-off part 12 of the outer periphery surface of the permanent magnet 5.  Therefore, the interval between the permanent magnet 5 and a stator 11 can be reduced when the magnet rotor 1 is built into the stator 11, thus is is possible to increase the output largely.

Title: Hard fiberscope
Inventor: TSUMANUMA KOUJI
IPC: A61B1/00
Filed: 1988-12-13
Abstract: PURPOSE:To easily insert the insert part of a hard fiberscope in a narrow part by curving said insert part. CONSTITUTION:All of the bending radius R and bending angle theta of the curved part 8' formed by curving the leading end part of the insert part 8 of a hard fiberscope and the length L of the curved part 8' when said curved part 8' is straightly extended are appropriately selected according to the use purpose of this hard fiberscope. For example, when the interior of a bent pipe is observed, the length L, bending radius R and bending angle theta of the bent part of the pipe to be inserted are respectively measured beforehand and the curved part 8' is formed so as to be fitted to the measured values. In a case diagnosing the internal organ of a human body, there is a slight individual difference in the internal organ or blood vessel of a human body but, since said internal organ or blood vessel has a definite bending radius R and a definite bending angle theta stastically, the curved part 8' is made fittable thereto. For example, in an arthroscope observing the interior of the joint of an arm, when the bending radius R of the curved part 8' is set to 15mm and the bending angle theta thereof is set to 45 deg., insertion becomes easy.

Abstract: PURPOSE:To detect fire quickly and accurately by building up a protective layer of an optical fiber with a meshed pipe or a bellows pipe breathing with the outside to increase an armor strength while enabling effective transmission of radiation heat and transfer heat to the optical fiber. CONSTITUTION:An optical fiber 2 of a temperature sensor 1 is protected by a meshed pipe or a bellows pipe 3 breathing with the outside as protective layer and hence, the sensor 1 makes up a firm armor with the meshed pipe and the bellows pipe 3.

Title: Heat exchanger using spiral fin tube
Inventor: KAWAMURA TOMOTSUCHI
IPC: F28F1/32
Filed: 1987-12-16
Abstract: PURPOSE:To miniaturize the size of heat exchanger, by laying out tubes in a staggering manner, and establishing the intervals of tube rows forming a right angle to the direction of gas flow, the intervals between tubes neighboring slantingly, and the ratio between the diameter of tube and the diameter of fin, within a specific range respectively. CONSTITUTION:Tubes 1 are laid out in a staggering manner. The center interval between a row of tubes 1 forming a right angle to the direction of gas flow F and tubes 1 neighboring to each other is defined as SL, the center interval between the tubes 1 slantingly neighboring to the direction of gas flow F is defined as SD. The diameter of tubes 1 is set as D while the diameter of fins 2 is set as Df. The tube layout condition is represented by formula I. When the draft loss and the quantity of heat absorption are assumed to be fixed, the space between the tubes 1 can be reduced, which reduces the flow rate of gas, extend the time in which gas remains between the tubes 1, and hence improves the rate of heat exchange per area. It is, therefore, possible to reduce the number of tubes 1, the height of fins and remarkably reduce the capacity of heat exchanger.
